Climate Change made easy

As you know by now from TV, magazines, news, commercial etc, there is this little problem that Humanity is facing called Climate Change caused by Greenhouse Gasses.
It's very simple. Some gasses which are considered good for our earth, such as CO2, methane and many more, lately went out of balance and they became not so good. Those gasses form a barrier around our planet, which acts as the glass in a greenhouse. They let in the worm energy coming from the sun and at the same time they keep part of it from going back out, keeping our planet at a temperature where life can exist. Nowadays we are having too much of those greenhouse gasses so they are keeping too much heat on the earth. Every time we use energy from fossil fuels, or a forest is destroyed/burnt or a cow pass gasses (sounds funny, but this is the reality!), we emit more of the greenhouse gasses in the atmosphere and we reduce the ability to capture those gasses back by the plants. The temperature rise and the ice at the poles melt releasing even more CO2.
We have more frequent extreme weather conditions such as draught and flooding, hurricanes, etc (NOAA June 2008 report on “Effects of a Changing Climate on Extreme Weather Events in North America” http://www.noaanews.noaa.gov/stories2008/20080619_climatereport.html). With the draught we have more wildfires, which destroy more trees and release more CO2. It is a vicious cycle.

Some countries will have a warmer weather (we may have wine from England, we may be capable to go from Europe to America from the North Pole by boat), but the positive changes will not be able to offset the negative ones that will or are already appearing in many countries (USA included), with catastrophic life losses especially in the undeveloped and/or more populated ones (Asia and Africa). On top of the severe weather, our crops and forests, the base of every life cycle, will be affected, because the plants are the last one to migrate, as they do not have legs, fins or wings to migrate. We will experience a global scarcity of food, massive movement of people, more diseases, losses in wildlife species, etc.
Unfortunately Climatology is not a precise science yet and it’s still very difficult to predict exactly where and/or when we will have the negative effects and how intense they will be.
For example scientists were expecting North Pole to be melted in about 30 years, and now they predict will be melted for a short time already at the end of this summer 2008 and completely in a few years (http://www.cnn.com/2008/WORLD/weather/06/27/north.pole.melting/).
You may feel discouraged from all those news, but there is also a big good new: the scientists tell us we have some time, not too much, to reverse this trend, and we have the resources, the technology and the human ingenuity to succeed. They also tell us that it is not just a problem of governments and businesses. It is mostly a problem of each one of us. So let's try all together to preserve our beautiful earth for our children, grandchildren and future generations.
